Overhead Channel Dimensioning• Simulated a packet-by-packet scheduler to generate assignment
statistics.• SSCH dimension: 12 total assignments, power control bits for 200
users, and ACK/NACK for 30 RL channels 22% FL overhead.• Resource utilization is shown not to be affected by 8 FLAB constraints.• Typical scheduling load is much less than the maximum dimension.

Outline• Report II Requirements:
– Traffic mix simulations.• Overhead channel modeling.• QoS arbitration.• Performance of each individual QoS class.
– Mobility and handoff• Performance of Salient Features:
– Antenna techniques.• MIMO Multiple Code Word with Successive Interference Cancellation.• Precoding.
– System enhancements.• Quasi-Orthogonal Reverse Link (QORL).• Fractional Frequency Reuse (FFR).• Spatial Division Multiple Access (SDMA).
– Estimate spatial structure of all intra-sector users.– Additional estimation loss due to QORL is modeled.– Other sector interference is modeled as spatially uncorrelated.
• Results are conservative– Same multiplexing order for all users.– No user clustering has been implemented in simulations.
FL SDMA• Channel model: pedB@ 3km/h.• Spatial correlation: suburban macro.• Codebook size: 2• Users select one beam at the beginning of each simulation run.• MRC: no estimation of spatial structure of intra-sector and inter-sector
interference.• MMSE: spatial processing based on estimate of spatial structure of
